A man is four times as old as his son. Five years ago, the man was nine times as old his
son was at that time. What is the present age of a man ?
66 years
40 Years
50 Years
35 years
Explanation:
Let sons age = x, then mans age =4x.
9(x - 5) = (4x-5) or x=8.
Mans present age = (4x + 7) = 35 years
Let sons age = x, then mans age =4x.
9(x - 5) = (4x-5) or x=8.
Mans present age = (4x + 7) = 35 years
